Fast, Reliable Bathroom Remodeling Across San Martin
A full bathroom remodel in San Martin typically runs $9,000-$28,000, with walk-in shower installations starting around $4,500 and tub-to-shower conversions from $3,500. What drives the final number here isn’t labor alone - it’s the age of your home, the condition of the subfloor, and whether your property sits on the expansive adobe clay that defines this part of Santa Clara County. If you live off Columbet Avenue, along Foothill Avenue, or up on a ranch parcel off New Avenue, call us at (877) 610-1318 and we’ll walk you through exactly what your bathroom needs. Barrett & Sons has been doing this work since 1998, and Tom Barrett’s sons run the crews you’ll see in San Martin.
Why Barrett & Sons Construction Is San Martin’s Preferred Bathroom Remodeling Company
San Martin isn’t a big city, and that’s the point. It’s an unincorporated rural enclave where your neighbors know your name and your contractor’s name matters more than a brand logo. Tom Barrett publishes his name, his address, and his license number - look it up before you sign anything. We’ve worked on ranch estates, vineyard homes, and 1970s custom builds across the 95046 ZIP, and we know what those houses do over time.
Our crews are background-checked and they carry the Barrett & Sons name on their shirts. When Tom’s sons show up on a San Martin job, they’re the same people you’ll see at the hardware store in Morgan Hill on a Saturday. That’s not a corporate slogan - that’s how we’ve operated for over 29 years.
Calls to (877) 610-1318 are answered by a live person, around the clock. Not a voicemail box. Not an out-of-state call center. If you’ve been burned by a national outfit that quoted one price on the phone and handed you a different bill at the door, you already know why that matters.
San Martin’s permitting runs through Santa Clara County’s planning and building department, not a city building office. We pull permits on every eligible job and we’re comfortable standing next to the county inspector. The permit inspector works for you, not for me - that’s why I like him. Every price change we make comes as a written change order before work proceeds. An allowance that isn’t on paper is a surprise waiting for a date.
Our Bathroom Remodeling Services in San Martin
Full Bathroom Remodeling
A gut-and-rebuild master bath on a San Martin ranch home means working with old studs, adobe-swelled walls, and subfloors that have shifted over decades. We handle the whole thing: demo, rough-in, plumbing, tile, glass, cabinetry, and final trim. Because San Martin homes often sit on expansive Pacheco-series soils, we check slab elevation before any finish work goes in. Skip that step and you’ll be looking at cracked tile within a few wet-dry cycles. Our full bathroom remodels in San Martin run $9,000-$28,000, fixed in writing before we order anything.

Walk-In Showers & Shower Remodeling
Walk-in showers are the most requested upgrade we see in San Martin’s 1960s-to-1990s homes. Owners want to lose the tub, gain a bench, and never climb over a threshold again. We install Schluter waterproofing systems, Kohler and Sterling fixtures, and frameless glass enclosures that actually fit - which matters when your walls aren’t perfectly plumb after 50 years of adobe movement. Walk-in shower installation in San Martin typically runs $4,500-$12,000.

Tub-to-Shower Conversion
Converting a tub to a shower sounds simple. On a San Martin slab home, it rarely is. The drain location, the subfloor condition, and the wall flatness all have to be checked before we quote. We’ve pulled tubs out of 1970s homes off Foothill Avenue where the plumbing was set for a tub’s high drain, not a shower’s lower one. That’s the difference between a two-week job and a two-month leak. Tub-to-shower conversions in San Martin run $3,500-$10,000, and we write every allowance into the contract before work starts.

Vanities, Tile & Fixtures
Custom vanities and architectural tile are where high-end San Martin bathrooms either come alive or go wrong. If your walls are out by three-quarters of an inch because the adobe clay under your slab has been swelling for 40 years, a stock vanity won’t sit right. We build custom millwork, set Wellborn cabinetry, install Grohe and Sterling fixtures, and lay tile on decoupled subfloors so it doesn’t crack when the ground shifts. Vanity installation in San Martin runs $800-$3,000, and tile work is priced by the square foot after we measure your actual walls - not before.

Trusted Brands We Service in San Martin
We install products you can look up, not mystery brands off a van. On San Martin bathrooms we regularly set Schluter waterproofing, Sterling and Grohe fixtures, and Kohler walk-in showers with frameless glass enclosures. We order premium-brand materials through our suppliers and we track long-lead items - like custom glass - from measure to install, so you’re not waiting on a shipping delay we should have seen coming. When a part arrives damaged (it happens), we swap it on our time, not yours.

Common Bathroom Remodeling Problems We See in San Martin Homes
- Adhesive clay swelling under slab foundations. The Pacheco-series soils under San Martin’s valley floor expand and contract with the wet-dry Mediterranean cycle. A perimeter-slab footing that was fine in 1975 can move enough by 2025 to crack floor tile and pop grout lines. We check slab elevation at rough-in and decouple finish surfaces where the movement is active.
- Permit sequencing that stalls the job. San Martin has no municipal water or sewer grid across much of the 95046 ZIP. That means bathroom remodels on well-and-septic properties need both a county building permit and a Santa Clara County Environmental Health clearance. If the well-septic review isn’t pulled early, the final inspection can’t be scheduled. We pull it at rough-in, not after.
- FAA Part 77 airspace rules near San Martin Airport. If your property sits within the airspace surface zones around E16, a bathroom addition that changes your roofline or footprint may trigger an FAA airspace determination before the county will issue a permit. Most out-of-area contractors never think about this. We do, because we’ve dealt with it on San Martin parcels.
- Wall flatness on old adobe-swelled studs. Waiting until finish carpentry to check wall flatness is the most expensive mistake we see. The custom millwork reveals the three-quarter-inch bow, and then the change order kills the design intent. We check framing and shim the walls before tile, glass, or cabinetry goes in.

FAQs - Bathroom Remodeling in San Martin
Yes, often both. San Martin is unincorporated, so building permits go through Santa Clara County’s planning and building department. If your home is on a well and septic system - common across much of the 95046 ZIP - the bathroom remodel also needs a clearance from Santa Clara County Environmental Health before final inspection can be signed. We pull both tracks early, usually at rough-in, so the septic review doesn’t stall your finish schedule. Call (877) 610-1318 and we’ll check your parcel’s specific requirements before quoting.
San Martin’s Pacheco-series adobe clay swells in winter and shrinks in summer. That movement transfers to your slab, and your slab transfers it to your floor tile. Large-format tile on a rigid mortar bed is the highest-risk choice. We recommend decoupled subfloors, smaller tiles, or stone-look porcelain with flexible grout in bathrooms where the slab movement is active. We measure slab elevation during rough-in and build the floor system to survive the wet-dry cycle. Call (877) 610-1318 for a floor assessment before you buy tile.
Probably, and here’s why. Many 1970s San Martin ranch homes were built on perimeter-slab footings, not the pier-and-grade-beam foundations standard today. After 50 years of adobe swell, those slabs are often out of level by half an inch or more, especially near exterior walls. If we tile over that without reinforcing the wet zone, you’ll get cracked grout and cracked glass within a few seasons. On a 1980s estate off Columbet Avenue, we found the original vanity wall out by nearly a full inch. We pier-and-beam reinforced the wet zone before any finish work. That’s the difference between a bathroom that lasts 30 years and one that fails in three. Call (877) 610-1318 and we’ll inspect your slab before quoting.
Order the glass at rough-in, not at finish. A custom frameless enclosure measured from your actual, post-tile walls takes 10-12 weeks from measure to install in San Martin. If you wait until the tile is done to call the glass company, you’ve added three months to your punch list. We measure, order, and track the glass schedule alongside the rest of the build so the enclosure arrives when the bathroom is ready for it. Call (877) 610-1318 and we’ll walk you through the sequencing from day one.
Because the allowance that isn’t on paper is a surprise waiting for a date. On a high-end San Martin bathroom with custom millwork, architectural glass, and designer-selected tile, the difference between a box-store allowance and the actual Caesarstone, Kohler, or Wellborn product the client chooses can be thousands of dollars. We write every scope, every allowance, and every price change as a written change order before work happens - so there’s no invoice shock at the end. Tom Barrett’s name is on the contract, and our 90-Day Done Right Promise is written on every job. Call (877) 610-1318 for a free estimate - you’ll get a written line-item quote, not a handshake and a wish.
